Why do windows have two panes of glass separated by a layer of air

Physics
1 answer:
Soloha48 [4]3 years ago
7 0

Air is a poor conductor of heat.  The air trapped between the two panes is a pretty good <em>insulator</em>.  It does a lot to prevent heat from flowing through the windows ... keeping heat IN during the Winter, and OUT during the Summer.

Nitella [24]

Answer:The electric field is zero and the potential is positive.

Explanation:

Two identical positive charges are separated by a certain distance and midway between charges two identical positive charges are placed near each other.

So the Electric field at midway is zero because the electric field due to both charges add up to give zero electric field.(because they point in opposite direction)

Potential is scalar quantity and charges are positive so they add up to give potential.

While walking along the shore of a lake Travis felt a cold breeze. What type of heat energy transfer is this an example of?
AfilCa [17]
Out of the 3 types of heat transfer, this scenario would be most likely to be an example of convection.

Convection is where the transferring of heat is resulted through the movements of fluid, but in this case it is air. What happens is that when a part of the whole mass of air is heated, the hotter air rises and the cooler air descends and takes place of the hotter air before it was heated. Then, the cooler air becomes hotter and the hotter air before becomes the cooler air of both, which then results to the repeat of the exchange of places. This creates a motion until the whole mass has achieved mutual temperature, the heat source has stopped or extinguished, or there is a shift of temperature.
